Large-Format Additive Manufacturing with Metallic Materials – Materials Review

Abstract

This chapter introduces material-oriented topics related to large-format additive manufacturing with metallic materials. The scientific interpretation of material response on the topics listed below is provided with the basis of physical metallurgy: deposition process, postprocess heat treatments, mechanical properties, environmental compatibility, and combined technology. Given the high deposition rates with high-speed wire feedstock and potentially unlimited build volumes, wire-base Directed Energy Deposition Additive Manufacturing processes are explored and compared with the powder-based AM as necessary.
